Improvement in life-boats



UNITED STATES I ATENT LAWRENCE F. FRAZEE, OF JERSEY CITY, NEW JERSEY, ASSIGNOR TO HIM- SELF AND JOSEPH J. WALTON, OF NEW YORK, N. Y.

N LIFE-BOATS.

Specification forming part of Letters Patent No. I 67,160, dated August 31, V1875; application filed August 4, 1875.

To all whom it may concern:

Beit known that I, LAWRENCE F. FRAZEE, of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Life-Boats; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference bein g had to the accompanyiu g drawings, and to the letters of refe-rence marked thereon, which forma part of this specication.

The nature of myrinvention consists in the construction and arrangement of a life, surf, and working boat, as will be hereinafter more fully set forth.

In the accompanying drawing, Figure 1 is a transverse vertical section of lny life-boat, taken through the line y y, Fig. 2. Fig. 2 is a longitudinal vertical section of the same, taken through the linea: 00,*Fig. l.

My life-boat is constructed of a series of separate and independent air-chambers, as follows: The sides of thel boat are formed of two elongated chambers, A A, of suitable shape, connected to the bow air-chamber B and stern air-chamber C, leaving a large opening in the center. The outer sides of the chambers A B C are extended upward, as shown, to form the usual sides. In the large opening in the center of the boat is placed an air-chamber, D, connected to the surrounding air-chambers by ribs a a, or other suitable means, and leaving spaces between them to admit the water. Above this center airchamber D is built a protecting-deck, E, which extends on all sides over the surrounding airchambers, and forms the bottom of the boat. It will readily be seen that, Whetherthe center air-chamber D is used or not, the water within the boat under the protectingideck E will stand as high as the Water surrounding the boat, whichprevents, or at least lessens, the liability of the boa-t upsetting. The additional air-chamber D materially increases the buoyancy ofthe boat. The various parts of the boat may be made of any suitable material, but I prefer to make the fore and aft pieces of iron.

Having thus fully described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

The protecting-deck E, in combination with the air-chambers A, A, B, and O, and with or without theV center air-chamber D, substantially as herein set forth.

In testimony that I claim the foregoing as my own I aiix my signature in presence of two witnesses.
